A camera module (170) includes a miniature scanning mirror (120), lens elements (163a to 163d) corresponding to thin lateral lens slices, and a short, wide imaging sensor (165). As the scanning mirror (120) pivots to scan a scene, the imaging sensor (165) captures successive image segments. Multiple image segments are stitched together by software running on a digital processor to provide a complete image. The assembly of lens elements (163a to 163d) may include moveable elements to allow variable focus, variable magnification and image stabilization, and may utilize refraction, reflection, diffraction and / or planar optical elements. The camera module (170) may be less than 5 millimeters thick while allowing long focal length lenses and increased light collecting area. Other embodiments include a switchable scan mirror with two apertures and a dual-camera system that provides binocular images and video.

A method and device for regulating the transport of material in a sewing or embroidery machine (1) that uses information from a position or movement sensor (33) located underneath the throat plate (21). The controls for the sewing machine (1) calculate deviations of the actual feeding increments of the article to be sewn from the corresponding target values from the periodically read sensor signals. With this information, the feeding increments are regulated in such a way that the deviations are cancelled out by averaging.

A dual ion trap mass analyzer includes adjacently positioned first and second two-dimensional ion traps respectively maintained at relatively high and low pressures. Functions favoring high pressure (cooling and fragmentation) may be performed in the first trap, and functions favoring low pressure (isolation and analytical scanning) may be performed in the second trap. Ions may be transferred between the first and second trap through a plate lens having a small aperture that presents a pumping restriction and allows different pressures to be maintained in the two traps. The differential-pressure environment of the dual ion trap mass analyzer facilitates the use of high-resolution analytical scan modes without sacrificing ion capture and fragmentation efficiencies.

A method, apparatus for executing the method, and computer program products for use in such an apparatus. The method includes scanning an interrogating light across multiple sites on an array package including an addressable array of multiple features of different moieties, which scanned sites include multiple array features. Signals from respective scanned sites emitted in response to the interrogating light are detected. The interrogating light power is altered for a first site on the array package during the array scan, based on location of the first site or on a determination that the emitted signal from the first site will be outside a predetermined value absent the altering (which allows for protecting a detector against expected overly bright sites), or is altered during the array scan based on the detected interrogating light power (which allows for compensating for light source drift during an array scan).

This invention relates to tandem mass spectrometry and, in particular, to tandem mass spectrometry using a linear ion trap and a time of flight detector to collect mass spectra to form a MS / MS experiment. The accepted standard is to store and mass analyze precursor ions in the ion trap before ejecting the ions axially to a collision cell for fragmentation before mass analysis of the fragments in the time of flight detector. This invention makes use of orthogonal ejection of ions with a narrow range of m / z values to produce a ribbon beam of ions that are injected into the collision cell. The shape of this beam and the high energy of the ions are accommodated by using a planar design of collision cell. Ions are retained in the ion trap during ejection so that successive narrow ranges may be stepped through consecutively to cover all precursor ions of interest.
